Article: OpenUI for Voice Agents: Pairing LiveKit with Generative UI for Real-Time Visual Feedback

Addresses #6

What this covers

A hands-on, code-first tutorial that walks through building a voice agent with LiveKit and OpenUI, based on reading and running the voice-agent-generativeui reference implementation.

Sections:

1. The dual-output architecture — how a single LLM call produces both audio and visual output concurrently
2. Pipeline vs Realtime modes — trade-offs between modularity and latency, when to pick which
3. Building the Voice Agent — the voice.Agent subclass with tools wiring
4. The show_ui tool — fire-and-forget streaming, abort-on-new-call, data channel transport
5. Receiving the stream in the browser — progressive rendering via C1Component
6. Bidirectional actions — how UI clicks flow back through the agent loop
7. Prompt engineering for multimodal output — when to use voice vs visuals, how to structure content
8. Setting it up yourself — prerequisites, clone/configure/run, common setup issues
9. Production deployment — LiveKit Cloud, performance metrics, scaling the visual path
10. What to build next — domain-specific agents, multi-user sessions, persistent visual history

Differentiators

• Covers both agent modes (pipeline + realtime) with concrete trade-offs
• Includes actual code from the reference implementation with explanations
• Troubleshooting section for common setup issues
• Production deployment guidance with performance benchmarks
• No marketing filler — every section has working code or concrete data
